It would be interesting to compare the profit per unit for Samsung and Apple. Clearly, Samsung is making it up in volume, which is frankly an impressive feat. Lower cost doesn't always translate to higher profits.

I hear you. And it seems like it's been a while since Apple totally revolutionized a product category. But the company has done it four times. That's not to say it will necessarily do it again. But still, that's a pretty impressive track record. Maybe Apple is going through a lull, or maybe the magic left with Steve Jobs. But either way, Apple is well positioned to continue raking in the profits for years, at least.
